The mechanism of vortex-induced oscillation of bluff section is closely related with the instability of separated shear around its body. The shear layer can be easily stimulated by self-movement of the body or external disturbance such as flow perturbation, applied sound with a specified frequency fluctuation and so on.In this study, the investigation of vortex-induced oscillation for 2-D rectangular section was performed by the way of shear layer instability stimulation by applying sound. Furthermore, geometrical shape effect on the response characteristics of the vortex-induced oscillation of edge girder bridge section was also investigated on the basis of applied sound technique.Additionally, the effect of turbulence on vortex-induced oscillation was fundamentally investigated by use of applied sound technique from the turbulent frequency effect point of view. |
